Yu et al. (Reports, 10 March 2017, p. 1072) state that contagious itch occurs in mice based on imitative scratching in normal mice observing excessive scratching in genetically modified demonstrator mice. However, despite employing multiple behavioral analysis approaches, we were unable to extend these findings to normal mice observing the well-established histamine model of acute itch in demonstrator mice.

评《小鼠传染性瘙痒行为的分子和神经基础》

余等人。（报告，2017 年 3 月 10 日，第 1072 页）指出，基于正常小鼠模仿性抓挠，观察到转基因示范小鼠过度抓挠，小鼠发生传染性瘙痒。然而，尽管采用了多种行为分析方法，但我们无法将这些发现扩展到正常小鼠身上，观察到在示范小鼠中建立的急性瘙痒组胺模型。
